A resource tree not nested under `/clusters/{cluster_id}` is + authenticated but **not** authorized per-tenant. Edge resources must either nest under + the same path shape or we replace the parameter coupling with a real tenancy abstraction. + 2. Cluster-secret auth enumerates **all clusters** per request and compare-digests each + (`_auth.py:107-132`) — O(#clusters) per API call. Fine at 10 clusters, not at 500 edge + sites. Needs a keyed lookup (secret→cluster index or token embedding the cluster id). +- CLI: `cli.py` is 100% generated from `cli-reference.yaml`; adding an `edge-cluster` command + group is one YAML block + methods in `clibase.py`.

An edge-local + CSI driver's projected SA token is meaningless to the central CP. Edge API clients must use + cluster-secret auth (see 1.2 gotcha #2) or the CP must run TokenReview against the *edge* + cluster's API — feasible, but new code. + +### 2.2 The snode-API gap is small for edge — because of partitions + +In k8s mode today, the CP calls the node agent, and the **agent** calls the k8s API from +inside the cluster (renders `storage_deploy_spdk.yaml.j2`, creates Jobs/Pods). So the +yaml-render + Job/Pod machinery already exists — it just sits on the wrong side of the wire. +Moving it CP-side is largely a relocation. + +Of the snode API surface, already replaceable with k8s API + SPDK RPC: + +- SPDK pod start/kill/is-up → create/delete/list namespaced pod (code exists in + `api/internal/storage_node/kubernetes.py`). +- Node liveness → `list_node` Ready condition; the pattern already exists in + `mgmt_node_monitor.K8sNodeBackend` (storage-node monitoring today is ICMP + snode API + + RPC — no k8s involvement; edge inverts that). +- Port block/unblock → `port_block.py` already prefers the SPDK RPCs + (`nvmf_port_block/unblock/get_blocked_ports`); the iptables fallback is legacy. + +The irreducible residue is (a) hardware discovery (`info()`/`scan_devices` — PCI NVMe lists, +NUMA hugepages, RoCE mapping) and (b) privileged host mutations (vfio bind, `nvme format`, +gpt partitioning over NBD, hugepage/kubelet orchestration). **The edge design mostly sidesteps +both**: nodes contribute pre-existing free *partitions* consumed as **AIO bdevs** — no PCI +driver binding, no nvme format, no partitioning by us, no NUMA topology work. What remains: + +- A minimal discovery step: which partitions/devices exist and are free. One-shot privileged + Job (or init container of the SPDK pod) publishing to a CR/ConfigMap — not a resident agent. +- Hugepages: SPDK needs some; on 2 vCPU boxes decide between a small static hugepage + allocation in the node spec vs `--no-huge`. Init-Job pattern exists but currently loops + back through `/snode/apply_config` — the hugepage math must move into the Job image. +- DHCHAP/PSK key files (`write_key_file`) → project a k8s Secret into the SPDK pod instead. + +### 2.3 WAN/slow-uplink assumptions baked into the CP + +- Monitors poll per-node every 3–30 s with LAN-tuned timeouts (`is_live` timeout 5 s, + retry 1); runners poll the task table every 3–10 s per cluster. At hundreds of edge sites + over slow links this needs: per-cluster-class intervals, jitter, strict timeout budgets, + and sharding of monitor services by cluster set. The existing per-node-thread supervisor + pattern scales to nodes, not to 500 clusters × RTT. +- Long-running API writes are fire-and-forget **threads inside the uvicorn worker** (202 + + thread dies with the worker; no idempotency token). Acceptable on a LAN, bad over WAN — + edge operations should be JobSchedule tasks from day one, never request-thread work. +- Status semantics: mgmt-plane unreachability must not mark storage down. The hyperscale + monitor already learned this (`UNREACHABLE` counts only with data-plane quorum; + `get_next_cluster_status` in `storage_node_monitor.py`). Edge needs the same separation, + but the "peer quorum" concept degenerates at n=1/2 — the uplink being down is the *normal* + failure mode and must map to `unreachable` (CP view) while the edge keeps serving. + The proposed edge status derivation (all offline → suspended; one of two offline → + degraded; else active) is a ~50-line pure function — do **not** reuse the ndcs/npcs + arithmetic. +- Autonomy: with no CP-driven failover at the edge, everything that must survive uplink loss + has to be SPDK-native: raid1 auto-resync on leg reappearance, nvmf reconnects, and — + critically — **no CP-held lock or task lease may gate edge IO**. + +### 2.4 FDB / API footprint (the caveat from the thread, made concrete) + +- Per-request cluster enumeration in v2 auth (see 1.2) — first thing that melts with many + edge clusters. +- `get_task_by_id` whole-table scan; monitors iterating `db.get_clusters()` every tick; + events/tasks retention keyed to one cluster's monitor. All linear in cluster count. +- Status vocabulary is duplicated as pydantic `Literal`s in `api/v2/_dtos.py` — adding edge + statuses (`degraded` exists for clusters; fine) or new task function names breaks v2 + serialization if the Literal isn't updated in the same change. + +### 2.5 Data-path items to verify in the SPDK fork (not CP, but gating) + +- raid1 rebuild on leg re-add: supported; verify behavior when the leg is an nvme-tcp bdev + that reconnects (bdev re-registration vs new bdev name). +- **raid5f rebuild**: upstream SPDK raid5f historically lacks rebuild support. "Replace a + partition → rebuild via raid" and "later add a device under the raid5" both depend on + this — needs an explicit fork-capability check; raid5f grow/reshape almost certainly + does not exist and "add device" may mean recreate-and-resync. +- 2 vCPU: single reactor + app thread; consider interrupt mode / dynamic scheduler to not + burn a core polling on an idle edge box. + +--- + +## 3. Operator / CSI — high-level impact + +### 3.1 Topology decision (the "CSI across two clusters" question) + +A CSI driver cannot span clusters: the node plugin must run where kubelet mounts volumes +(edge), and the controller plugin's sidecars (provisioner/attacher/snapshotter) watch +PVC/PV objects, which live in the **edge** cluster's kube API. So: + +- **CSI deploys entirely per edge cluster** (controller + node parts), but its controller is + just an HTTP client of the central management API — point it at the central endpoint over + the uplink. No CSI code split across clusters. +- Consequence: CSI must tolerate uplink loss gracefully — provisioning stalls (acceptable), + but NodeStage/NodePublish and health of already-attached volumes must not depend on the + CP. Today's node plugin gets connect info from `GET /lvol/connect` at stage time; cache it + (or persist it in the volume context at provision time) so remounts/reboots during an + uplink outage still work. +- Auth: the driver authenticates with the edge cluster's secret (SA TokenReview won't work + cross-cluster, see 2.1). + +### 3.2 Operator + +- Aligns with the existing plan (per the thread): CP install becomes its own CRD; SPDK pod + management moves from sbcli into the operator. For edge, the **central** operator manages + remote clusters → it needs the same per-edge kubeconfig plumbing as the CP (2.1), or — + simpler — a thin edge-local operator instance that only reconciles pods/yaml while the + central CP stays the source of truth. Recommend the latter: it keeps "edge keeps running + standalone" true for pod restarts too (kubelet restarts pods anyway, but CR-driven changes + queue up). +- New CRD: `EdgeCluster` (or `StorageCluster` with a profile field): nodes (1–2), per-node + device/partition list, uplink endpoint + credential ref. CR write-back + (`patch_cr_status/…`) must be parameterized by target cluster; today it hardcodes + in-cluster config. +- The CR contract is currently triple-encoded (connect-entry model, v2 DTOs, camelCase CR + patch dicts in `controllers/*_events.py`) and documented nowhere except e2e helpers — + edge is the forcing function to write it down before adding a fourth shape. + +### 3.3 Functions that don't exist at the edge (CSI/API surface diff) + +Available/unchanged: create/delete/resize volume, snapshots + clones on the local lvstore, +connect info (single path or the raid1-exposing node), QoS, encryption (KMS is central — +cache/lease DEKs edge-side or crypto volumes fail closed on uplink loss — needs a decision). + +Not available at edge (CSI/operator must degrade cleanly, API should reject early): + +- ha_type=ha multipath fan-out, secondary/tertiary roles, hublvol/JM machinery, distr — + the whole ultra data plane.

Both flows carry an + explicit-create fallback, but the fork behavior must be verified. +3. **Rebuild-progress fields** of `bdev_raid_get_bdevs` — `_wait_raid_synced` gates + fail-back on "2 legs present, no process/rebuilding marker"; align with the fork's + actual field names. +4. **1→2 node expansion** under an existing lvstore needs raid1-insert-under or an + offline migration; v1 rejects it (`add node` fails if a 1-node cluster already has + an lvstore). +5. **CSI**: capability-aware StorageClass + connect-info caching (analysis §3). +6.
